You can try this local TV repair shop to see if they know anyone:
Universal Electronics

Or a local amateur radio operator group might be a good place to ask questions. They may even do it for a free meal.

Just tell them what you are looking for and see if they know of any service. I'm hesitant to suggest satellite installers because of past experiences.
Also be prepared, when having someone else do the install, they may give you a completely different antenna(s) recommendation. Quiz them about why they choose what antenna and why. Make sure they give you good answers.
Good luck.
